These Ablocksl are movable radially inward into 4engagementwith the `outer face of the rim to vshrink this rim to size as well astofshape the rim.4 yFor movingthe blocks there are the cams 8 which aresecuredtoand depend from the yholder 3,

there beingonecam for each block. Eachk cam has the cam face 9 which isengageable with the roll 10 carriedupon theouterend of ablock. and theface 11 'engageable with the roll 127 which is spaced yradially voutwardfromI 4the .roll 10 yand is carried by Ithe Aabutymen-t Vmemberljmount'ed upon; and lsecured tozthe bolster 2.'- Foryp'ositivelyrnoving the blocks radially outward fand away from the rim,the-cams 8are provided attheir opposite sidesvwiththze-cam faces 14which are yengagef able with thepins -15 in: axialI alignment with eachother and 1 secured to lthe bifurcations 16 attheouter ends of theblocks. Y v For .perforating therim'l to form the hole for receiving thevalve stein of the pneumatic tire, I'have providedthe slide, 17 upon oneof I' the blocks 4,' thisslide being movable radially'inwardtoward'ftherim andcarrying the punch 18 Which y is engageable `with the .rim 1 tovperforate the same. The slide 17 is moved `bothltowardeand away fromthefrim positivelywby meansofgthe cam .19 whichis secured to landdependsv from the holder 3 and has the cam face 2O engageable with theouter endfof the slideto move 4the latter. radially inward'and-the. camfaces 21y at its opposite side'sengageable with'the .pins 22 upon the.

rbifurcations23 at the outerl end ofthe slide 1 for moving the Islidevradially outward. 'The cam19 is so arranged relative to the cams 8 thatthe blocks 4 are kmoved radially inward to their-predetermined sizingpositions prior to thetime the `cam 19 foroesthe punch 18 throughtthebase of therimfy 24 is a die for cooperating with the punch 18, this diebeing v carried uponthe radiallyfmovable slide 25 which is y'mountedupon the supporting block 26- andguidedby suitable gibs secured-tothisblock. This block' restsfupon' and is secured Y to the bolster The slideV25 is movable ra-A dially outward to carry the die 24 into engagementwith the inner face of the rim and this slide is forced radially outwardby means of the cam 28 which is vertically Vslidably mounted fupon thecentral block 29. This block is located centrally ofthe holder 3 andsecured thereto and the cam 28 is yieldably forced downwardly and awayfrom the holder by means Iof the coil spring 30 having its upper endvabutting the holder andV its lower Y endabutting the cam. Formoving theslide 25 radially inward to disengage the die 24 ,from the rim, I haveprovided the coi-l spring 31 which is located intheiecess 32 inthe c 1supporting-block 26.and has its outer endengaging anend of .this VrecessAand its innerend engaging thepin 33 secured to the slidev 25.

VVith this arrangement, the die 24 is yieldably Vforced against theinner `face of the rim to f cooperate with the vpunchl8 and consequentlythis die does not interfere withthe opera-V tion of the sizing blocks4in shrinking the rim..`VV f1 For perforating the' baseV of the rimYnear its ends. to formv holes for receiving the, rivets which securethecooperating interlocking plates to the yrim vends, I .have providedthe pairs ofve'rtically aligned punches 34 on oppositesides of thisplate. {These punches are carried by theradiall y movable slide 35 whichY cured :to and'depeds'from theholder 3 and is mounted upona sizingblock 4. For moving this Vslide radially inward'to bring the punchesinto eVngagt-iment with: the rim' to perforate the same, Vthere is thecam 36 which is sehas the camV face .37' engageablel with the outer endofthe slide 35V and arranged so that the Y punches arebroughtinto/engagement with the rim `afterthe' sizing 'blocks have beenA moved totheir predetermined sizing position.

For moving the slide 35Yradially outward to disengage the punchesrcarried thereby from the rim, the'cam 36 is provided at its opposite.sidesV Withthecam faces 38 whichareen-Y A gageable Vwiththe axiallyaligned pins* 39V upon the Vbifurcations40- at'theffrea'r endof theslide V35.Y YF or backingv upf the rim .durin'g Y Vfthe operation ofthe-punches 34,V I have .pro-

vided the die l41' which` is carriedby the 4radially movable slide 42upon the supporting block 26. Thisslide is yieldably moved ra- Y Vdiallyoutward to bring the die into engage- 5'5 yment with the inner face oftherim' by means of thefcam 43 which :is vertically slidablymountedrupon the` centralblock 29. upon the holder, the camloeingyieldably forced down?Y wardlyV and vaway .from'the' holder by means ofthecoil spring 44 and the Varrangement being such that the vdie4lmaycooperate with 'i .l the pun'chesf34` without interfering 'with theoperation of the sizing blocks 4. The. slide 42 is yieldablyforcedradially `inward by.y means of the coilfspring 45-which islocated withinfthe recess 46 in the Aclock 26. Y t v For perforating theV rim to formholes Y therein for receiving the rivets of the clamping lugs which areto be permanently attached to the rim, I have provided slides A4whichVare radially movable and'mounted upon certain of the sizing blocks 4,theupperfaces of these blocksjbeing inclined inwardly Vand 'l areengageablewiththe innerendfwalls of the openings .to force thesameradially inward after the sizing blocks have been forced radir allyinward to their predetermined sizing por. sitiOn. For returning theslides 47 to their original positions and disengaging the punches 48from therim, the vcams 8*.jare .prosV l i' vided with the cani faces 5lwhich areengage-y able with the rolls 52 mounted fin thegslides 47 atthe outer ends ofthe openings.:k For backing up the rim Ihavejprovidedthel dies 53 which are carried by theradially movable Aouslides 54. These slides are mounted upon the v supporting block 26, theyupper face ofwhich with the slides so thatthe latter move paral.

' hasinclined bearing portions for engagement 3 '.lel to the slides47..v The slidesl54 areforced Y` Y A radially outward to bring theirdiesf53 into: f i

contact with the rim by means of the cams 5 5. which, are l verticallyvslidably :mounted upon the central .blockz29kiThe cams55 are forcedVdownwardly and away from the holder by means of the Vcoil springs `56sov that the A Y u dies'may back up the rimY without' interfering Vwiththe operation of the sizing blocks 4. For

moving they slides 54. radially inward toldisengage their diesfrom therim, there arethe Y Y Y coil springsv 57 which 1- are located vin therecesses58 formed in the upperface of the sup-k porting block 26.
